Answer to Question 1

ANS: D
The initial physiologic response to a burn injury is a dramatic change in circulation. A precipitous drop in cardiac output precedes any change in circulating blood or plasma volumes. A circulating myocardial depressant factor associated with severe burn injury is thought to be the cause. Metabolic acidosis usually occurs secondary to the disruption of the body's buffering action resulting from fluid shifting to extravascular space. There is a greatly accelerated metabolic rate in burn patients, supported by protein and lipid breakdown. With the loss of circulating volume, there is decreased renal blood flow and depressed glomerular filtration.

Answer to Question 2

ANS: A
The immediate threat to life in children with thermal injuries is airway compromise and profound shock. Anemia is not of immediate concern. During the healing phase, local infection or sepsis is the primary complication.
